Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Cypriniformes Cyprinidae

Scientific Name: Hypsibarbus suvattii Rainboth, 1996
Taxonomic Notes: The distributions of both ranges of both H. suvattii and H. lagleri are both unusual and require confirmation through further research. Records from outside the Mae Khlong basin are uncertain, due to its morphological overlap with H. lagleri, a Mekong endemic (C. Vidthayanon per. comm. 2011). The specimen from the Dong Ngai in southern Viet Nam is larger than specimens from the Mae Khlong, but it in other ways did not equate to H. lagleri; however, the population here may be a third species and a series of specimens would be required to resolve the uncertainly (W. Rainboth pers. comm. 2011).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2012
Date Assessed: 2011-03-08
Assessor(s): Vidthayanon, C.
Reviewer(s): Rainboth, W. & Allen, D.J.
Contributor(s): Fisher, J.
Justification:
There is limited information available on this species. Records from outside the Mae Khlong basin in Thailand possibly pertain to another species and further research is required to confirm this. Although it is thought to be declining due to threats in the Mae Khlong, this decline is poorly known, and it is assessed as Data Deficient.

Geographic Range [top]

Range Description:The species is known from the Mae Khlong (Thailand), from where it was described. Records from elsewhere, including the Dong Nai (Viet Nam), southeastern Thailand (coastal Gulf of Thailand drainages; Doi 1997) and coastal rivers of the Cardamom mountains (Rainboth 1996), are uncertain and require confirmation, but may be remnants of a once continuous population pre-dating the last glacial period (W. Rainboth pers. comm. 2011). The species possibly occurs in the Mekong but has not yet been recorded there (Rainboth 1996), but see Taxonomic Notes.
